The cars have all been unloaded with almost no problems, two cars do have damaged mirrors.



A last minute check:


The cars are then lined up for Qualifying.


The NSR cars really suited this track. The big surprise was that the NSR's responded very well to being cleaned with Enviro Friendly water!



IMO these positions will change a lot come race time,a couple of the quick cars are hard to drive.

Beejays car must have been in the UK winter as the tyres still seem frozen. Sports Racer has not listed his brand of tyre BUT they could be some kind of almost round wood.

Now to clean the rest of the shed and finish some other Proxy cars before Tuesday nights race.

First Corners car is very fast and good to drive. Should do well IF the drivers can come to grip with the power.

I qualified the cars BUT hope to have enough drivers Tuesday that I won't have to drive.

Cheers Phil.....Nice to know things can only get better... .

I guess the tyres are just like their owner.....it's been a cold winter over here......but I'm off to thaw out in the Canaries for a week on Sunday....Woopee.

I think the big mistake you made was not laying down a line of lighter fuel and setting fire to it by spinning the rear wheels, that would have thawed them out....I blame Quantas...that chepo Aussie airline for unheated holds...

The tyres are not SCX by the way, but Pauls Slot Car Shop Erethanes from Canada....They work very well on my track but obviously not on yours.... . A light sanding helps....

Looking forward to the race where I'm sure my car will crawl ahead of that awful slow F40 thing.

Regards

Alan

I will correct the tyre info, gee you have just saved me some money! I was looking at getting some to try. The Ortmans seem to worl O/K just goes to show there are so many different Urethane compounds around.
Enjoy your "holiday" I thought every day was a holiday now.

[first corner crash]

Woo hoo. That is a great result so far. I wasn't expecting it to go that well on such an undulating track being a relative lightweight. I wsa thinking it might go better on bigger more open tracks. The motor and gearing is one i used for running at BMR in a slot it Nissan and it holds the track record there in that class. I changed from a King evo and slightly bigger gears just before sending the car off and it may yet still prove to be a bit over motored especially if there are drivers that arrent used to this kind of setup. It takes a bit to get in the groove and keep it out of the wall.

Obviously not an MJK stronghold

Youre on your own Trevor, no more help from me mate. I should be taking tips off you. Sorry mate I accidently put a hammer though that SCX NASCAR you wanted me to look at. Hope you dont mind.

Looks like NSR is the go in the podded and non podded class

[kalbfellp]

There was lot af variation in grip with the MJK cars. Some were good BUT a few had no grip at all. Do they change with age or different batches?
The Zonda is fast BUT very hard to drive smoothly,I think drivers will have problems with it. Watch Boss 302 car on race night,easy to drive very consistant.

I'm no expert but find the MJK's perform a lot better with a quick "Burnout" on a wet/damp rag before a race. One to get a bit of heat into the tyres and two to clean any dust on them. Usually do a few warm up laps then clean them before the start. (One final lap first to dry them out!)

[FANGIO]

well, our portion of the dupr is under way. good luck to all.
thanks for the q run phil.

[oswald900]

Thanks for the update Phil

Middle of the pack but not much in it

Can not wait for the green flag to drop and all this Bull S%$t stops

There is some degrading of MJKs - once they have been used - normally due to contaminants

[kalbfellp]

Ontheflipside Do you know the difference between MJK and NSR? Your car is listed on the proxy site as MLK but is fitted with NSR's. Just as well for our tracks by the look of it.

8 out of the top 10 running NSR would seem to back that up but the race is a marathon not a sprint and the guys that speak about the RAA say the NSR tyres tend to dry out and lose grip as they get older so we will see. I have some old formula ortmans to run in that race so i am interested to watch Espix's car as the motor and gear ratio is not dissimilar to what i am running. So the tyre performance will be interesting.Plus this is only one track and I think NSR is the dominant tyre anyway so there are always going to be a few at the pointy end of the field. As for the nascar Rick if the motor actually revolves at anything like the rpm it is supposed to after your magic tuning I might be nice and lend you a spare GTone car when the class comes up( i have a few good ones) and you can leave the bouncy one in the box. I set this car up at Tbirds originally and the tracks there tend to be bigger and flat and the changes i made werent huge so it may well be a bit of a handful on some of the circuits here. Still its all about learning. As an aside I have seen both photos and a video of Phils track but some of the others i have no idea about. Will the track owners post photos of the tracks when doing their reports? It would be helpful if possible.

I have run MJKs for quite a few years now and yes they do loose their grip level as they age , it could be due to the material hardening a bit over time ( Rick technical answer on that here please) mostly I put it down to a build up of contaminants over time , I mean a fair bit of time as well , some of my MJK tyres have been on for over 9 months . Usually a buff on sand paper fixes them up but if they are old and greasy they often don't seem to recover very well , and new MJKs are noticably better but as they are new and freshly glued on and slightly buffed in using 600 grade wet rub I would expect them to be better than the worn out old tyres.
I often clean my braid before a race night with 2.26 on a rag and then with another rag I wipe the braid over , I end up with lots of blackish/green stain on the second rag . Then I run my track cars around for a while to clean up the braid and ferrodore surface before people arrive to race I do it because Im close to the beach and the track may be left unused for a month sometimes .

PS I like the the photos Phil

You trying to stir things up again Steve?

[kalbfellp]

The MJK and NSR cars were run at different times but all cleaned the same. I was surprised with the NSR's they actually went better when cleaned with the water and detergent! I would imagine that it would dry them out over time.
But some of the MJK's had very little grip.

[BMR]

With all the talk about tyre comparisons I thought it may be worth revisiting this thread again .
There is a rumour these tyres could be on the market again around the end of this month - bit late to put them on a proxy car though

Absolutely not. tyres can get crap on them just by putting them back in the box, fingering them with oilly hands ( sounds rude but . . . .)

New MJK s are a very good tyre - old MJKs are not so good - just a fact of life

Its no diffrent than Flycar tyres going rock hard. Mind you they only go rock hard after they have oozed crap and lost their shape - sort of like rigor mortis sets in after a while.

Likewise elsewhere - foam tyres go off even when not used hence as PK said you keep them in the fridge.

Steve get onto Neil and tell him its time to recalibate the 5 gallon bucket he uses to mix the urethane.
